Hi Manish,
Can you provide some more detail on this data? How are you getting it? Is it read from a text file? Is it generated by another command? It is data a collection of objects or an array of strings? I could make some assumptions based on how the data looks, but it would be just that, assumptions. If it's an object, then it is very possible that the property is already in datetime. If it's a string, you may be able to convert it to day time by simply type casting the string as datatime
